It is among the objects of this invention to H PI'OVldG a simple, compact and convenient wrench combining 1n one appliance thefunc tion'of a wrench and the advantageous fea- "s tures of a ratchet wrench, alsoto provide a reversible ratchet-wrench that may be used 1 ,for screwingbo'ltsor nuts into place or un screwing the same, and also to provide improved adjusting means for the jaws ofthe 10 wrench. j i

. Further objects'andhadvantages may appear in the following detailed description, taken in connection with the-accompanying drawings illustrative of the invention, in

1 which the same reference characters indicate i' the same parts in all of the views:

Figure 1 is a top plan view of the invention, showing but a fragmentary portion of' i the handle. u p

20 Figure 2 is a section taken onthe line 22 of Figure 1, showing particularly the four operative screws. 1 j

Figure 3 is a section taken on the line 33 of Fig. 2, showing especially the insert'able androtatable operating handle of the device.

. Referring now to the drawings, the adj ust- I able' ratchet socket wrench comprises a revolvable and pushable handle which handle is provided with a reduced tubular portion 11. This tubular portion 11'is slid- .ably held in the sleeve 12 by means of an upturned collar 33 or by other suitable means and the tube 32 has a similar upturned end thereby limiting the outward pull of the handle with the relative parts. On the sleeve 12 there is a retaining ring 13 which ring holds cam collar 14in proper relation with the end of pawls 15, said pawls 15 being pivoted at pawl pivot 16 on a substantially an; nularshell head 25, next to and adjacent to the cam collar. In View of the fact that the pawls 15 are of conventional structure and of conventional operation it is believed that further description, operation and illustration of said pawls is not required. 7 Of course the annular shell head 25.is in non-movable relation with the handle, but 7 this annular shell head houses a revolvable with suitable guide blocks 17 which blocks are preferably formed integral with the ring D 24',-so that the jaws-18 and 19 may be properly jguided when the jaws are in'movement in being urged awayv or toward each other. In I order to urge the aws 18land 19 away or to-;" 55 ward each other within thering 24, four op.- erative screw 20 cooperate 'therewith as' to be deescribed hereinafter and each ofv said J screws is providedwith right and left hand threads, and set parallel to each'other, as well-60 i as in threaded engagement with'the jaws 18 "and 19. '1 The ends of'these'operative screws 20 furthest away from the 1 handle 10, are -.set indepressions'22Iand 23'of ring 24 and the opposite ends of these operativescrews 20 65 ,are provided with-rotatable gears 29 and said 'r'otatable'gears29 areadapted to be actuated by lthe. meshing teeth 30 'of an internal gear =21,,whichinternal gear21-is adapted to be rotated on the: fixed collar 31, which collar 10- has a central opening and fits-into the recess '27 of-s aid'igear 21".. It will be seen that the in- ;ternal gear mayv manually be rotated by' the application of the thumb thereon,or it may be 1 revolve d'or rotatediby the insertion of square (7, end .34 of pushable and rotatable handle 11, into. the, centrally located square hole 28 of the-internal gear 21L A suitablespring surroundssquare end 34 so that upon release ,of'pushing pressure, the disengagement be- 280 tween thesquare end34 andsquare hole28 is quickly accomplished W-When it is, inan engaged. position; the de'-' vicemay be used as a ratchet wrench, since ratchets 26 aresuitably provided on the outer .85

cylindrical surface of the ring 24 that properlycQOperateswith pawls l5, cam collar 14, and likewise are also reversible by theprovi sion of two pawls 15.

7 It will be obvious that the general structure V hereinbefore set forth may be modified in certain particulars and it is to be understood that the invention isnot accordingly limited to such specific structure except as hereinafter claimed.

Having thus described the invention what is claimed as new is':- 1. An adjustable ratchet socket wrench comprising a shell head, a ring ratcheted in said shell head, a pair of blocks having paral- "190 lel opposed guide faces provided in said ring, a pair of wrench jaws disposed between said guide faces and having a plurality of inter-i nally threaded openings therethrough, the

threads in one of said jaws being right-handed and those in the other of said jaws being left-handed, a plurality of correspondingly threaded screws passing through said oppositely threaded openings in said jaws, said 7 screws being rotatable in said ring at one end, a rotatable gear aflixed to each screw at its other end, a fixed collar projecting into said ring, an internal gear riding on said collar and having its teeth in mesh with each said rotatable gear, whereby rotation of said internal gear will adjust said j aws.

,2. An adjustable ratchet socket wrench comprising a shell head, a ring ratcheted in said shell head, a pair of blocks having parallel opposed guide faces provided in said ring, a pair of wrench jaws disposed between said guide faces and having a plurality of internally threaded openings therethrough, the threads in one of said jaws being right-handed and those in the other of said jaws being left-handech'a plurality of correspondingly threaded screws passing through said oppositely threaded openings in said jaws, said screws being rotatable in said ring at one end,

a rotatable gear affixed to each screw at its other end, a fixed collar projecting into said ring, an internal gear riding on said collar and having its teeth in mesh with each said rotatable gear, whereby rotation of said internal gear will adjust said aws, a handle tube projecting from said shell head, a handle slidable on said tube, shoulders limiting the sliding movement of said handle, a spring urging said handle to the limit of its movement, said handle having a polygonal shaped portion projecting into said handle tube, said fixed collar in said shell head having an opening therethrough to admit said portion, said internal gear having a socket opening corre sponding in shape to said projecting handle portion, whereby, when said openings are aligned, said handle may be pressed into engagement with said internal gear'to adjust the same.

In testimony whereof I have affixed my signature.
